APPARATUS FOR DYEING, SCOURING, OR OTHERWISE TREATING YARN ANI) OTHER FIBER-S IN THE HANK OR SKEIN.

Application lled August 5, 1921, SerialNo. 489,935. Renewed June 22, 1923.

T0 all "Uilm/m, it may con-cern.'

Be it known that I, ItIowAnn M. DUDLEY, a citizen oi the United States, and a resident of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Apparatus `for Dyeing, Scouring, or Otherwise Treating Yarn andOther Fibers in the Hank or Skein, oi which the following is a specification.

My invention relates more particularly to that type ot machine in which the banks or skeins of yarn or liber to be dyed or otherwise treated, are. Suspended from sticks and dip into a closed tank or chamber containing the dyeing or treating liquid, and in which provision is made for the movement of such liquid; preferably in aplurality of directions, in order that all portions of such skeins or hanks ot yarn or other fibers shall be sub- `iected equally to the action of the dyeing or treating liquid.

The principal object ot my present invention is to provide means disposed exter nally oit' the dyeing or treating chamber for eitecting movement of the liquid therein; which means may include a liquid containing casing in liquid tight engagement with the dyeing or treating chamber and containing passages in communication with the top and bottom ot the same; with a propeller disposed in said casing for effecting movement of the liquid for passage in oppositedirections in said dyeing or treating chamber as may be desired.

A further object of my invention is to provide battle plates in the upper and lower portions ot the dyeing or treating chamber in order that the moving liquid may be prevented trom Jforming currents that would tend to avoid portions Yof the yarn or fiber under treatment; such batiies breaking up the moving liquid and insuring engagement therewith of all portions of the hanks or skeins of yarn or fiber under treatment.

In my present construction, I employ a vertically movable frame or support for the yarn or tiber-carrying sticks, as in my companion application, such frame or support being so mounted that when the dyeing or treating liquid is being moved in one direction, it will have a tendency to litt said sticks, and the yarn with the same, and in such action will cause a separation between the sticks and the yarn supported thereby at the point of contact, whereby such contact- 'ingportioin which is more 0r less diiiicult ot liquid within the dyeing or treating chamberv are locat-ed ywholly outside said chamber`- so that while the liquid may be moved in two directions within the chamber, the circulation is from an vouter casing into the chamber, and from the chamber to such outer Casing. In other words, the casing receiving the propeller or liquid moving member is disposed outside the dyeing or treating chamber, and provided with passages leading to the upper and lower portions ofthe latter; the liquid for instance, when discharged into the upper portion of the chamber, leaving the latter from the lower portion thereof and passing to the external casing, and when introduced into the lower portion of the chamber, leaving the latter from the upper portion thereof and passing into the external casing.

These and other features of my invention are more fully disclosed hereinafter; reterence being had to the accompanying drawing, in which:

Figure l, is a longitudinal sectional view of dyeing or fiber-treating apparatus within the scope ofmy invention.

F ig. 2. is a cross sectional view 0n the line II-II, Fig. l. y

. Fig. 3, is a cross sectional view on the line IIIIII, Fig. l, and A -Figs. 4L and 5 are detached views illustrat ing details of my invention.

My improved apparatus is of the closed chamber type, whereby the dyeing or treating liquid within the same may be moved in a plurality ot directions; that is to say. downwardly through the hanks or skeins ot yarn or fiber, and then upwardly through the same; changes in direction of movement ot the liquid being eii'ected readily and without altering the character of the power-applying means, which are disposed eXternally'- ot' the dyeing or treating chamber.-

In the drawing, 1 represents the dyeing or treating chamber, which may comprise a suitable base 2, and side and end walls 3 and 4, with removable top or cover 5, in liquid-tight, or substantially liquid-tight en- `@agement with the side and end walls of the chamber, so that under the motion imparted thereto, the liquid within the chamber will have no tendency to leak or seep out beneath the top or cover 5. lVithin the chamber so provided, the-banks or skeins ot' yarn or fiber, indicated at X, are disposed toi' treatment.

The hank or skein supporting means disposed within the dyeing or treating chamber are suspended by bolts 10 connected to the cover 5, and are substantially like those disclosed in my companion application tiled ot even date herewith. Such supporting means may comprise end cross-bars 11, to which said bolts 10 are secured; said cross-bars carrying at their opposite ends boXes 12, for the reception ot the ends ot rails 13, extending the length of the dyeing or treating chamber, said rails being apertured at 14, for the reception of yarnoi liber-carrying sticks 15, which are held thereto by the retaining plates 16, constructed and operated in the manner set forth in my companion application, and confined against lateral movement. Provision is made for slight vertical movement of said sticks; the boxes 12, in which the ends of the rails 13, carrying said sticks, are disposed, providing space for' vertical movement of the rails, and said sticks follow with them. In addition, theV crossbars 11, supaort aV oraminous trame disposed directly over the hanks or skeins ot varn or fiber, through which the moving liquid passes; such frame being made up ot' side rails 20, and cross-bars 21, spaced a suitable distance apart. As this arrangement is more or less common in apparatus ot this character, it would seem to require no specific description as to exact character or function.

Supports 22, depend from the boxes 12, and adjustably carried by the lower ends ot these supports, are rails 23, secured to the supports by pins 24, and having cross sticks 25, which pass through the lower portion ot the lianks or skeins of yarn or fiber and restrain the saine troni excessive upward movenient when the .liquid in theV chamber is caused to move in an upward direction, and litt the hanks or skeins of yarn or liber from the upper sticks. Below the hanks or skeins of yarn or fiber, I provide a oraminous Jframe comprising side rails 20, and crossbars 21a, of the same general character as the frame disposed above the hanks or skeins ot yarn or liber, and designed to perform the saine function as said upper `frame.

'Disposed externally of the chamber, I proV- vide means tor moving the liquid througl' the dyeing or treating chamber OPPQSLA.-

directions, such means including a casing 30, of special character, having a mid section 31, substantially circula-r in cross-section, which mid section broadens outwardly and ilattens toward the upper and lower portion of the dyeing or treating chamber to forni the passages 32 and 33, the discharge outlets 32 and 33a, thereof, being substantially rectangular and elongated and registering with ports or openings 34 and 35, formed in the end wall 4 of the dyeing or treating chamber. 'I he combined inlet and outlet ports or openings 34 and V35 are disposed above and below the hanks or skeins of yarn or fiber, and such ports or openings have an area substantially equal to the cross sectional area or" the circular mid portion ot said casing, intermediate the passages 32 and 33.

Suitably disposed in the casing 30, preferably at the circular mid section ot the same, is a propeller wheel V40, carried by a shaftr 41, which may be journaled in suitable bearings 42 and 43, carried by the casing, and

motion to turn said shaft may be imparted by a belt 44, passing over a pulley 45, car- Y ried by the end ot said shaft 41, and driven by a motor 46. When drivenin one direction, that indicated by the arrow a, for instance,the liquid will be driven in the direction indicated by theV arrow ai; being drawn out of the lower portion of the dyeing or treating chamber through theport 35, into the passage 33, and discharged by said pro- Y peller through the passage 32, and port 34,

into the upper part of said dyeing or treating chamber. When the wheel is driven in the direction of the arrow Z2, the liquid will be driven out of the top Vot the dyeing or treating chamber through the port 84, into the passage 32, into the dyeing or treating chamber in the direction ot the arrows y, in-Y f dicated by dotted lines.

In order that the liquid may be prevented y cated at 47 being carried by the top or cover l 5 of the dyeing or treating chamber, whileV Y those indicated at 48 being carried at the bottom of the chamber. It will be under-r stood, ot course, that a. greater ork less number of baille plates, capable of performing the desired function, may be employed, as desired. Y

In practice, as I have described in my companion application, the hanks or skeins ot yarn or fiber will be lifted from the upper ,l

sticks when the dyeing or treating liquid moves in one direction, permitting complete contact of the liquid with all parts of said hanks or skeins of yain or fiber, and such xction is illustrated in Figs. 4 and 5.

CII

While I described a propeller mounted upon a horizontal shaft and disposed in the circular mid section of the external casing for moving the liquid in the dyeing chamber, it will be understood that such propeller may be mounted upon a vertical shaft; the casing being modified accordingly, and such shaft being driven so as to move the liquid from said casing through the dyeing or treating chamber in two directions. In all instances, however, such movement of the liquid takes place in a casing disposed externally of the ldyeing or treating chamber.

While I have shown in the drawings ports or openings 34 and 35, formed in the end wall 4, ot' the dyeing or treating chamber and which register with the combined inlet and discharge openings 32 and 33 of the external casing respectively, as rectangular in shape-and not extending the entire width of the dyeing or treating chamber, itwill be understood that their shape maybe changed or altered as may be desired, that in some instances it may be oval, and that in other instances where rectangular openings are provided, it may extend the full width of the chamber without departing from my invention. The appended claims are intended to cover a structure having an opening for the purpose described, capable of performing the desired function.
